Polypropylene for precision injection molding applications

摘要

The present invention is a nucleated, metallocene catalyzed polypropylene homopolymer with an MFR less than 100 g/10 min, or desirably less than 21 g/10 min, the polypropylene useful in making casting cups and other such articles where a high degree of precision and accuracy in the casting is desirable, such as in contact lens casting cups.
